Cylindrical Roller Bearings FAG NU2313 -E-XL-K-TVP2
The FAG NU2313 -E-XL-K-TVP2 cylindrical roller bearing, measuring 65x140x48 mm and featuring a tapered bore, offers high radial load-carrying capacity for demanding industrial applications.
This single-row cylindrical roller bearing NU2313 -E-XL-K-TVP2 from FAG, when used as a support bearing, can withstand very high radial forces. With a bore of 65 mm, an outside diameter of 140 mm and a width of 48 mm, it belongs to the wider 23 series. The design features a polyamide cage and a tapered bore with a taper ratio of 1:12. As an open rolling bearing, this model is designed for external lubrication with oil or grease.
In which bearing applications does the NU2313 -E-XL-K-TVP2 cylindrical roller bearing prove its worth?
This design is primarily used in bearing arrangements where only high radial loads need to be supported. Due to the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless. This allows the bearing to compensate internally for axial length changes of the shaft relative to the housing. The component functions purely as a non-locating bearing and does not support any axial forces.
How does the tapered bore affect assembly and adjustment?
The tapered bore, designated ‘K’ and with a taper ratio of 1:12, facilitates precise adjustment of the radial clearance during assembly. The cylindrical roller bearing can be mounted either directly onto a tapered shaft seat or onto a cylindrical shaft using a suitable mounting or withdrawal sleeve. As the inner ring can be removed from both ends, the inner and outer rings can be fitted separately, which facilitates installation in confined spaces.
What are the dimensions of the NU2313 -E-XL-K-TVP2 cylindrical roller bearing?
The bearing has an internal diameter of 65 mm at the bore, an external diameter of 140 mm and a width across flats of 48 mm. Thanks to the wide design of the 23 series, it offers an increased contact area between the rollers, enabling it to accommodate heavy radial loads during operation.
What does the NU design designation mean for this cylindrical roller bearing?
In the NU design, the outer ring has two fixed guide flanges for the rollers, whilst the inner ring has no flanges. This allows the shaft to move axially relative to the bearing housing in both directions. The bearing thus acts purely as a non-locating bearing and prevents axial stress in the machine system.
What are the properties of the TVP2 polyamide cage?
The polyamide material gives the window cage a low weight and damping properties. The designation TVP2 refers to an injection-moulded polyamide cage that ensures smooth operation. It is designed for operating temperatures ranging from -30 to +120 degrees Celsius and is compatible with standard lubricants.
How is a cylindrical roller bearing with a tapered bore fitted?
A bearing with a tapered bore (1:12 taper) is either pressed directly onto a tapered shaft journal or mounted on a smooth shaft using a locking sleeve. Sliding the bearing axially onto the taper causes the inner ring to expand, allowing the operating clearance to be adjusted with precise fit.
What is the clearance and tolerance class of this rolling bearing?
The bearing is manufactured with standard radial clearance (CN) and complies with the standard tolerances of class P0 or Normal (PN), which corresponds to ABEC 1. It is designed for standard applications where no extended clearance groups such as C3 or tighter manufacturing tolerances are required.
How is this open bearing lubricated?
As this is an open bearing without integrated sealing washers, it requires lubrication from the surrounding structure. Depending on the application, you can use either grease or lubricating oil. The outer ring has no ring groove or lubrication bore; the lubricant is therefore supplied from the side via the bearing housing.
